How to Restore Your Pool After a Storm

min read
Whether you're dealing with leaves, dirt, standing debris, or several inches of rainwater, taking the right steps after a storm can protect your pool and your equipment while getting your water back on track.
Step 1. Remove Debris Before It Becomes A Bigger Problem
The first priority after a storm is clearing the pool of leaves, branches, dirt, and other organic material. As debris sits in the water, it begins to break down, consuming sanitizer and contributing to staining, cloudy water, and algae growth.
Start With:
- Skimming large debris from the surface
- Emptying skimmer and pump baskets
- Vacuuming or using a robotic pool cleaner to remove settled debris
- Brushing pool walls and steps to loosen dirt
- The faster you remove debris, the easier it is to restore water chemistry.
Step 2. Run Your Pool Equipment
Once debris has been cleared, allow your circulation system to work. Running your pump continuously for at least 24 hours helps mix the water and improves filtration after heavy rainfall.
Inspect your:
- Pool filter
- Pump basket
- Skimmer basket
- Robotic cleaner filter cartridges
Storm debris can quickly clog filtration systems, reducing their effectiveness when you need them most.
Step 3: Test Your Water Clarity
Heavy rainfall often dilutes pool chemicals and changes water balance. Even if your pool looked perfect before the storm, don't assume the chemistry is still within range afterward.
Pay special attention to:
- pH
- Total alkalinity
- Calcium hardness
- Stabilizer (cyanuric acid)
Water balance should always be the foundation of your recovery process. Puri Tech's pool care system begins with balancing pH and alkalinity before moving on to sanitizing and corrective treatments.
4. Rebalanced pH and Alkalinity
Stormwater can push pH and alkalinity outside recommended ranges, making chlorine less effective and increasing the risk of cloudy water.
To restore balance, consider:
Puri Tech pH Plus Pool and Spa pH Increaser
If testing shows low pH following heavy rainfall, a pH increaser can help raise water back to the proper range for more effective sanitation.
Puri Tech Total Alkalinity Increaser
When total alkalinity drops, pH levels can become unstable and difficult to maintain. Alkalinity increasers help create a stronger chemical foundation and support long-term water balance.
Maintaining proper pH and alkalinity is one of the most important steps in preventing future water quality issues and protecting pool equipment. PuriTech specifically highlights pH balancers and alkalinity control as the foundation for clean, balanced water.
5. Check Calcium Hardness
Large volumes of rain can also affect calcium hardness levels. Water that is too soft can become aggressive and potentially impact pool surfaces and equipment over time.
Puri Tech Calcium Hardness Increaser Plus
This product helps restore calcium hardness when testing indicates levels have fallen below recommended ranges.
6. Rebuild Stabilizer Levels
Rainfall and overflow can reduce stabilizer (cyanuric acid) levels, making chlorine more vulnerable to degradation from sunlight. Adding stabilizer helps protect chlorine from UV loss and supports more consistent sanitizer performance throughout the recovery process.
7. Santized and Monitor
Once balance has been restored, test chlorine levels and sanitize as needed according to your pool's requirements. Continue testing water over the next several days to ensure chemistry remains stable.
According to PuriTech, balanced pH, proper chlorine levels, and correct alkalinity help maintain clean water while supporting the longevity of pool equipment, including robotic cleaners.
Conclusion
Storms are unpredictable, but your pool recovery plan doesn't have to be. By removing debris quickly, testing water thoroughly, and restoring critical chemistry levels, you can get back to enjoying clear, healthy water sooner.
